LEEM-18 AC Bridge Experiment
Iimvavanyo
1. Funda kwaye ulawule iimeko zokulinganisa kunye nemigaqo yokulinganisa yebhulorho ye-AC;qinisekisa iimeko zebhalansi yebhulorho ye-AC;
2. Ukulinganisa i-capacitance kunye nokulahleka kwe-dielectric;self-inductance kunye ne-coil quality factor and mutual inductance kunye nezinye iiparameters zombane.
3. Yila iibhulorho ze-AC ezahlukeneyo zokulinganisa ngokwenene.
Iiparamitha eziphambili zobugcisa
1. Umthombo wesignali eyakhelwe-ngaphakathi: i-frequency 1kHz ± 10Hz, i-voltage ye-output amplitude: 1.5Vrms;
2. Isiboniso sedijithali esakhelwe ngaphakathi I-voltmeter ye-AC: Uluhlu lokulinganisa umbane we-AC: 0～2V, isiboniso sedijithali esinesiqingatha;
3. Imitha ye-digital frequency ye-LED eyakhelwe ngaphakathi eneedijithi ezine, uluhlu lokulinganisa: 20Hz～10kHz, impazamo yokulinganisa: 0.2%;
4. I-AC ye-zero-pointer eyakhelwe ngaphakathi: kunye nokukhusela okugqithisiweyo, akukho ntloko yemitha;ubuntununtunu ≤1 × 10-8A / div, ukulungelelaniswa ngokuqhubekayo;
5. Ukumelana nengalo yebhulorho eyakhelwe-ngaphakathi:
I-Ra: iqulethe ukuxhatshazwa kwe-AC ezisixhenxe kwe-1, 10, 100, 1k, 10k, 100k, 1MΩ, ngokuchaneka kwe-0.2%
I-Rb: Iqulunqwe nge-10 × (1000 + 100 + 10 + 1 + 0.1) Ω ibhokisi yokumelana ne-AC, ngokuchaneka kwe-0.2%
I-Rn: Yenziwe nge-10K + 10× (1000+100+10+1)Ω ibhokisi yokumelana ne-AC, ngokuchaneka kwe-0.2%
6. I-capacitor ye-Cn eyakhelwe ngaphakathi, i-standard inductance Ln;
Umthamo osemgangathweni: 0.001μF, 0.01μF, 0.1μF, ukuchaneka kwe-1%;
I-inductance esemgangathweni: 1mH, 10mH, 100mH, ukuchaneka kwe-1.5%;
7. Ukumelana nokulinganisa i-Rx, i-capacitance CX kunye ne-inductance LX kunye namaxabiso ahlukeneyo kunye nokusebenza kubandakanywa.
